.Application filed September 13, 1913, Serial No. 789,643. Renewed March18, 1915. Serial No. 15,386.

To all whom z't may concern r Be it known that-I, ORLANDO E. KELLUM, acitizen of the United States, residing at Los Angeles, irthe county ofLos Angeles, State of California, have invented new and usefulImprovements in Sound Transmission and Recording, of which the followingis a specification.

This inventionfrelates toa device for. -transmlttlng and recordingsound, especially in making .sound records for use in talking movingplctures; and the invention consists in the novel features of the sound`transmitting and recording device and broadly in the combination olf-such device-"with a synchronously operating moving picture camera; theprime object of the invention beingthe easy and efficient production`,gf synchronous sound kand visual .chronously reproduced in recordswhich may be subsequently synproper Acorrespondence to each other.

In its now preferred form, my invention Includesja sound recorder andelectrlcal transmission apparatus; said transmlssion apparatus includinga telephonie transas to be easily engaged by the contacts mounted uponthe person while the mitter or the like placed upon a person, atelephonlc receiver or the like coperating with the sound recorder, andelectrical connections between the transmitter and receiver of suchnature as to allow the-person to move within the field ofview ofthemotion picture camera and to be audibly in connection with the soundrecorder. These connections may be made in a variety of manners so as tobe invisible yor practically invisible to the motionypicture camera.I I

.prefer to use contacts mounted upon the person and contacts which arestationarily 'distributed about the field of view. The

stationary contacts ymay be distributed so assumes natural poses atwill;the contacts either being in the fiooror; on the various `furniture inthe vicinity, or both. AnL l. other means which I may. use will includealine Wire connection directlyfrom the person -to the recorder, or ,theelectrically actuated apparatus thereof, said Wires being of a size andcolor to not be discernible in the motion picture.

I have shown preferred forms of my apparatus in the accompanyingdrawings, in which, l

Figure 1 is a view partly in perspective person and partly in diagramshowing my com- IE `lete arrangement in its preferred form,

ig. 2 is a diagram showing the electricaly l arrangements thereof, Fig.3 is la view showing a possible construction Nof the sound recordingapparatus, Fig. 4 is a diagram illustrating a modified form ofapparatus, with a telephonie. relay included therein, Fig. 5 is adiagram showing such a telephonie relay as I may use, Fig. 6 is a detailshowing a method ofmounting a contact upon the person, and Fig. 7 is aview similar to Fig. 1 showing the connections made from the person tothe sound recorder by'direct wiring.

In the drawings the numeral 10 desig- 'nates' a sound recordingapparatus, 1 1 a moving picture camera and 12 a 'personl whose actionsand speech it is desired to record. The movingpicture camera l1 and thesound recorder 10 are operated synchronously, being connected by meansofA wires 13 so. that they operate together. This species of synchronouscoperation may be the same as s hown in my Patent No. 1,027,658.' dated'May 28th, 1912. In the preferred form of my synchronousoperatrecording-stylus 15, the diaphragm 16, and I a means 17 lforelectrically transmitting to the .diaphragm the sound vibrations whichare originallyproduced by the speech -of a person and. which areultimately recorded upon the record 14. The device 17 may be of anydesired character, and may coperatewith the recording stylusl in anymanner.

A s a simple arrangement, I have shown' a telephonie receiver apparatushaving a dia'- phragm 18 and electromagnet 19, the'magnetically causedvibrations of the diaphragm producing sound Waves which impinge upon vthe stylus diaphragm 16; or the arrange- .lnent may be made to combinediaphragme.

16 and 18 into a single diaphragm. The arrangement illustrated has theadvantage of taking the weight of thetelephonic receiver apparatus ofi'the stylus.

los

Wires 20 and 21 connect tothe receiver, Y

and Ythe wires may include in circuit, asis shown in Fig. 2, a battery22.' From V,wires 2O and 21 branch wires 20 and 21a lead to variouscontacts 23 and '24, which may be distributed about the space in whichthe person is moving. These contacts 23 and 24 may be placed on thevfiner .or furniture and the wires 20% and 21' may pass-beneath thecarpet or rug or may be concealed in other manners; or they may be ofsuch color and of so small diameter asto be invisible or practicallyinvisible in thefinal motion pic-` ture. The contacts 23`and 24 may bemade small so as to be unnoticeable, or may be built into the variousfurniture in such man-l ner as to apparently form parts thereof. It

is only necessary that one of contacts 23 and one of contacts 24 beconnected with in order to establish a complete circuit; and

these contacts may be engaged by finger contactsor footcontacts on theperson, or by both.

The personal equipment vof my device consists preferably in a suitabletelephonic transmitter 30 which is placed in any Suita-hleposition Vonthe person, being placed against the persons chest and either held inposition by a suitable belt 31 or by. mere pressure of the clothing.Various wires 20b and 21b may proceed :trom the opposite sides of thetelephonie transmitter and may terminate in suitable contacts 26 and 27which may be mounted in convenient positions on the person. vAsindicated, the contacts'may be mounted either on the hand or on thefoot; and in Fig. 6

I have shown in detail the mounting of a hand Contact. In -this ligure,the contact may consist of a thin flexible contact strip 31 mounted upona finger ring of ordinary appearance, the contact strip being on theinside of the linger where it is not noticeable and where it may beeasily engaged with the stationary contacts. fore stated, it is onlynecessary. that one set from the transmitterl 30 will lead'xto. bind.

ing'posts .41 and 42, and-the 4wires 20 and 21-c leadingvto therecording apparatus will lead from binding posts 43v and .44.. Thebattery 22 is used as in the device of 2, while-.auxiliary` battery 45isusedon the as `for instance y As hereinbeot contacts on each side ofthe circuit .be in engagement. Thus,A the circuit may run sistsessentially in adouble wound magnet 50 havinga, winding.. ,lfponnecteddirectly to the bindingposts 41` and 42. This double wound-.magnet:vibrates a vibrating armature 521whi'ch coperates with adjustablecontact.53, .the variations in the secondary Vnirren't f'the relay beingmade by variations. of resistance at" the contact 58. The winding 54 ofthe magnet 50 is in series with thecontact`53; and this series circuitconnectsdirectlv to the binding posts 43 and 44. This form of. relay iswell known tothe l art,l I'may use this form or any equivalent form. Ll

vInltigx 7 I have shown an arrangement practicallythe same as that shownin Fig. 1, vin whichI eliminate the. contacts 23, 24, 26and 27 andconnect the transmitter 30 lon the person directly with the recordingapparatus by means ot line 'wires 20c1 and 21d.

These wires may be passed through the l' clothlng of the person to theHoor and may then lie loosely'. on the floor and connect with the soundrecorder.- They may be of such color and such diameters as to beinvisible or'practically invisible in the ultimate moving picture. Y
